Apple is making it easier for customers to snag an iPhone 5s handset. The company has enabled its in-store pick up reservation system for the popular new iPhone. To buy your new iPhone, point your browser to Apple’s online ordering page for the iPhone 5s. Choose your color, capacity and carrier options, then click on the “Check Availability” link on the right hand side of the page. This will allow you to select your local store and check the current inventory of the iPhone 5s in that store as well as surrounding stores. If the model you want is in stock, you can reserve one for in-store pickup. If the model you want is not available, then keep checking back. Apple usually updates its inventory at 10:00PM local time each night and you might be able to secure one for the next day.
